Allow static mapping of sysLocation strings to coordinates.

At our company, we set system locations based on campus/building/room and intentionally don't use street addresses.

However, within the monitoring system we'd still like to use the map, with approximate locations.

So far the procedure is, to add static geocoordinates to the first device listed in a search for a specific location string. This usually puts all devices in that location on the right place on the map. However, this does not always work and breaks whenever we add a device with a alphabetically lower name to a specific room. (which happens quite often, unfortunately)

So something like this would be appreciated:

// Mapping (unknown) sysLocationstrings to geocoordinates.

$config['geocoding']['geocoding_map']['NY, TR44, R4983'] = '40.74926,-73.98549'; // sysLocation string / geolocation 

Also, I wonder if it is possible to adjust the match threshold for  the API used. I'd prefer a location like 'Mikes Office' to return Unknown, rather than some remote place on a different continent.
